AUXILIARY-AIR-INLET DEVICE FOR iNTERNAL-COMBUSTION ENGINES.

' Application filed March 28,

To all whom it may concern:

Be it known'that I, .S'rnn INo E WIL- BERGER, citizen of the United States, residing at Julian, in the county of Nemaha and State of Nebraska, have invented certain new and useful Improvements in Auxilia'ry-Air-Inlet Devices for Internal-Combustion Engines, of which the following is a specification.

My invention is designed to facilitate the combustion of liquid hydrocarbons in internal combustion engines when the latter are subjected to subnormal temperatures which tendfto retard and minimize such combustion.

. An object of the invention is to provide simple and eifectivemeans for heating both the air and fuel supplied to the engine, to the temperature required for most effective combustion, despite adverse atmospheric conditions; such means being attachable and detachable as an accessory to automobile en- .ginesof ordinary construction.

'. A further object of the invention contem lates means operating in conjunction with he intake manifold of the engine to supply thereto an auxiliary charge of heated air at each impulse of the engine piston, said aux- 'iliary air supply commingling with the combustible mixture prior to its passage into the engine cylinder.

The invention as a still further object, aims to provide means including a novel form-of heater, so arranged with respect to the exhaust conduit of the engine as'to utilize the high temperature of the exhaust or spent gases to heat the auxiliary air supply prior to its suction into the intake manifold.

The above and additional objects are ac- I compli'shcd by such means as are illustrated iritheir preferred embodiment in the accompanying drawings, described in the follow- 111g specification and then more particularly pointed out in the claim.

In describing my invention in detail refer- ;ence will be had to the accompanying drawtingsfwherein like characters denote like or corresponding parts thruoghout the several views, and in which Fi re 1 is}. side elevation illustrating thev application of the invention; Fig. 2 is an enis a section on the line of'Fi'g. 2. Before proceeding with the description oftthe drawings, I desire to callfparticular atspecification of Le tterl Patent.

tention to the fact that While I have evolved my invention with reference to its applicaencircle the conduit 5, it being held in spaced relation thereto through the medium of lugs or projections 8 formed integrally with and upon the inner periphery of said plate. Openings 9 are formed in the respective terminals of said plate, through which curved extensions 10 of a suitable band 11 extend, the said band, as is illustrated to advantage in Fig. 3 of the drawings, serving as a fastening means whereby the said plate 7 is held in place. Anair supply pipe 12 is connected' at one end to the heater 6 it being open to the space between the outer Wall of the conduit 5 and the inner surface of the plate member 7, the opposite end of said pipe 12 belng annularly elarged as indicated at 13 to provide for its attachment, by means of a packing nut 14 team extension 15 of a suitable valve casing 16. y

A second or lateral extension 17' is' integral with the casing 16, said extension being exteriorly threaded as at 18 to fit a threaded opening'19 of the intake manifold 3, the free end of said extension being out ata sharp angle and, when in operative position, being disposed interiorl .of the saidmanifold 3 directly in the pat of the fuel supply en route. to the cylinders 2. The casing 16, as is apparent upon reference to Fig/2, is hollow, and has arranged therein a valve. memberl'f', one end of Whicl1'.is 'shaped to close the bore 18- of the extension 15 communicating the pipe 12 with i the cas'ing 16 from that in communication tl1es aid(pi(pe 12 is opened, it being in; terrorly'threa e to receive a nut 19 having a'thre'aded bore 20 into which :is fitted an exteriorlythieaded extension 21 of aprime -the interior of the casing. The opposite end h1g1 cup 22-, said extension being-provided with :1 central bore 33 communicating-said cup .22 with the interior of said casing. A wire 24, of any suitub le type, is opei able to open and close communication between said cup and said casing,saidzxuli'e being olose the bore 23 in. the manner shown 111. the said Fig.2. Said preferably arranged to extension 17 is also providednith :1 control bore. whereby the interior of the, Casing 1U ma v,l e in communication with the in tei'ior of the intake manifold 3, from which v :irmingeniont, itig apparent that upon n ovo- .inent (lf filit pistonfi 'ithin the cylin 1ors 2 ,:j y. is su ckedf through the bore "25, hnd ;vith the fl llfillp T the air 'iiith'in the Casing ll) ply di-nnninto thosnid cylinder-s in a man; ner neoess nry to operation of theengine,
